INDUCTION COIL MOUNTING.

Application filed August 27, 1923. Serial No. 659,591.

To all whom it maig ooncemw Be it known that I, Riel-mun C. ROSE, a citizen of the United States, residing at Osceola, in the county of Mississippi and State of Arkansas, have invented a new and useful Induction Coil Mounting, of which the following is a specification.

This invention'has reference to inductance coil mountings especially designed for use in radio receiving systems, the primary ob- 'ject of the invention being to provide device of this character wherein the mutual inductance between the primary and secondary circuits may be varied uniformly throughout the entire areas ofthe coils.

Another object of the invention is to proi vide a device of this characterwhich may be used for either double or triple mounts for practically any conventional type of coils, means being provided to permit of minute adjustment of the mutual inductive fields. I

Another important object of the invention is to provide a coiled mounting constructedfor the reception of coils of various sizes, thereby adapting the device for various usages. T

WVith the foregoing and other object in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, Without departing from the spirit of the invention.

Referring to the drawings i I I F'gure 1 is an elevational viewdisclosing the mount constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a fragmental elevational view of the panel.

Figure 4 is a side elevational View of the device disclosing the same as supporting a plurality of coils.

Figure 5 is a sectional View taken on line 5-5 of Figure 4.

Figure 6 is a sectional view taken on line 6-6 of Figure 4.

Figure 7 is a sectional view taken on line 7-7 of Figure 1.

Figure 8 is a sectional view taken on line S-8 of Figure 1.

Figure 9 is a sectional view illustrating the connection between the coil and contact member associated therewith.

Referring to the drawings in detail, the reference character 5 designates a portion of a panel of a radio apparatus, on which the mounting is positioned.

Extending from the panel 5 is a supporting member 6 formed of suitable insulating material which supporting member is held in an upright position by means of the angle plate 7. Secured to the plate 7 are the clamping blocks 8 which are disposed in suitable spaced relation with each other to receive the extension 9 of the spider web coil 10. V

Arranged on opposite sides of the clamping blocks 8 are spring arms 11 which are formed with depressions 12 at points adjacent to their upper ends, which depres sions receive the contact members 13 carried by the inductance coil, whereby the circuit through the wires of the inductance coils will be completed to the arms 11' which are in circuit with the necessary leading-out wires. From the foregoing it will be seen that due to this construction the ceutral inductance coil is held in a stationary position. The reference character l-t indicates bearing members which are secured to the supporting member 6 at a point adjacent to the upper end thereof, which bearing members provide bearings for the operating rods 15 that have right angled (X-- tremities 16 to which are secured the lingers 17 the. opposite ends of the rods extending through the panel member 5 where they are supplied with operating knobs 18 that are supplied with dials 19 whereby the degree of rotation of the dials and movements of the arms may be accurately registered.

Secured to the panel 5 at opposite sides of the coil 10 are binding posts indicated at'20, which binding posts are formed with bearings 21 in which the extensions 22 of the coil support-ing frames 23 move to permit of rocking movement of the frames 23 and coils supported therein. As shown, the lower extremities of the arms of the frames 23 are secured to the insulating bars 24, thereby allowing the electric energy to pass through the arms of the frames 23 to the coils supported thereby. The coils supported by the frames are indicated at 25 and have bearings 26 that connect the coils to the frames in a manner to permit of pivotal movement of the coils within its frames.

An operating bar 26 is pi-votally supported on each panel at 27, and is formed with an opening 28 to receive the linger 1T associated therewith, whereby with movement of the finger and rod supporting the same, a relative movement of the operating har will be had. The upper end of the operating bar 26 has connection with the bearing member 26 of the frame 25 associated therewith, by means of the bar 29 so that movement of the bar 26 transmitted to the framefor movingthe frame andcoils supported thereby towards and away from the coil to vary the inductance of the coils.

Due to the connection between the bar and bearing 26' it will be obvious that as the arm 29 moves downwardly and the frame is moved away from the coil 10, the

frame 23 will swing downwardly and the frames will be swung on-their pivots in siich a way as to hold them in parallel relation with the coil 10.

While I have shown and described a triple mount, it is to be understood that one ofthe coils may be removed and the device used as a double mount.

From the foregoing it will be obviousthat as the operating knobs 18 are moved, the frames which are indirectly operated thereby, are moved towards and away from the central inductance coil, to the end that the mutual inductancebetween the primary and secondary circuits isvaricd uniformly throughout the entire areas of the coils.

The foregoing result is accomplished by the pivotal connection between the frame and coil supported thereby insuring the movable coils beingheld at all times in a plane parallel to the fixed coil.

I claim L An inductance coil mounting. comprise lug a. panel, means for removablymounting a stationary coil on the panehpivoted frames mounted on the panel, coils disposed in the pivoted frames, and means for moving the pivoted frames and coils supported thereby to cause the coils of the pivoted frames to move in parallel relation with the stationary coil.
